How to process xml data from server using DataManager and bound to Grid

Problem

How to process the XML response from server and bound the result to Grid?

Solution

Essential Javascript DataManager works well with JSON data, but when comes with xml, we need custom adaptor to achieve this requirement. In the custom adaptor, the processResponse has to be overridden to process the xml response from the server.

In the below code snippet, we have extended processResponse method of the ej.UrlAdaptor and in the extended method, the xml data from the server is converted into JSON array. Now it can bound with grid. In the following code, we have performed simple Xml to Json conversion in the function “ConvertToJSON”, which will parse the simple xml document to json, for complex xml parsing, you can use external libraries.

Now let us see, how to use the above custom adaptor (named xmlAdaptor) in the grid. Render the grid and assign the custom adaptor to the grid datasource in the grid Load event.
